Compute effective DPI (eDPI) as DPI × in-game sensitivity and, when you change hardware DPI, the matching sensitivity that keeps the same eDPI. Everything is typed math in your browser — there is no mouse access, no driver APIs, and nothing is uploaded to DroidXP, the same local-only stance as APK Analyzer and APK String Extractor. Use results as a starting point, then confirm in-game.
Enter your mouse DPI (from your software or specs) and the sensitivity shown in one game’s menu. Formula: eDPI = DPI × sensitivity.
If you move from one DPI to another and want the same effective sensitivity, use:
new_sens = (old_DPI × old_sens) ÷ new_DPI. Valid ranges: DPI 100–32000, sensitivity > 0.
Competitive and FPS players often talk about DPI (dots per inch the sensor reports) and in-game sensitivity (how the game scales those counts). Multiplying them gives a single number — effective DPI (eDPI) — that is easier to compare when two people use the same game’s sensitivity model. This page does not read your mouse: you type values, and the math runs locally, like unpacking logic staying in the tab on APK Analyzer.
eDPI = DPI × sensitivity — use for one title at a time when its menu uses a simple linear scale.new_sens = (old_DPI × old_sens) ÷ new_DPI — keeps DPI × sensitivity unchanged so turn rate stays similar before you
fine-tune by feel.
Different games use different internal scales, yaw, and sometimes non-linear curves. Do not assume eDPI transfers cleanly between Valorant, CS2, Apex, and others without a title-specific converter. Raw input, pointer precision, and acceleration can all shift how movement feels even when the algebra matches — treat outputs as starting points and validate in a practice range.
No hardware access, no telemetry payload: numbers you enter stay in your session like text you paste into APK String Extractor. Loading this page only pulls normal static assets from DroidXP.

No. This page only multiplies numbers you type — there is no device access and nothing is sent to DroidXP, similar to APK Analyzer staying local.
Effective DPI is commonly defined as mouse DPI multiplied by in-game sensitivity when the game uses a linear multiplier. It is a shorthand for comparing setups — not identical across every title.
Not reliably without game-specific conversion — scales and yaw differ. Use this tool for one game’s linear model at a time, or look up official converters for cross-title matching.
If eDPI = DPI × sensitivity stays constant, a higher DPI needs a lower in-game sensitivity and vice versa. The calculator solves for the new sensitivity given your old pair and target DPI.
OS acceleration and some raw-input paths change how counts map to rotation. Treat results as planning numbers and verify in a training range.
No — centimeters per 360° depends on each engine’s yaw and units. This page sticks to DPI × sensitivity algebra unless you add your own constants elsewhere.
Yes. Games often store fractional values; enter what your menu shows (use dot as decimal separator).
Yes: inputs stay in the tab. Only normal static assets load from DroidXP like any page.
No — vendor software or OS settings change hardware DPI. This is a reference calculator only.
Pros cite what they run in-game plus hardware DPI; eDPI compresses that pair into one comparable number when the model is linear.
